He asserted himself over the other Lithuanian nobles and tribal chiefs in 1236, was baptized in 1251, and was crowned King of Lithuania on 6 July 1253; he was murdered in 1263.[1](https://www.britannica.com/biography/Mindaugas) • [2](https://www.lrt.lt/en/news-in-english/19/1445400/coronation-of-lithuania-s-king-mindaugas-fact-fiction-and-politics)\n\n| Key fact | Detail |\n|---|---|\n| Rule | Ruler of Lithuania from 1236/1238 until his death in 1263[1](https://www.britannica.com/biography/Mindaugas) • [3](http://fmg.ac/Projects/MedLands/LITHUANIA.htm) |\n| Baptism | Latin-rite baptism in 1251, mediated by the Livonian Order[4](https://erenow.org/postclassical/crusades/643.php) • [5](https://erenow.org/postclassical/oxford-history-poland-lithuania-volume-i-making-polish-lithuanian-union-1385-1569/4.php) |\n| Coronation | Crowned King of Lithuania on 6 July 1253[6](https://www.ldkistorija.lt/the-last-medieval-kingdom-the-coronation-of-mindaugas/) • [7](https://www.xn--meb.pisz.pl/Kr%C3%B3lestwo_Litwy_(1251%E2%80%931263)) |\n| Death | Murdered in autumn 1263, with his sons Ruklys and Repeikis, by Daumantas of Nalšia acting for his nephew Treniota[3](http://fmg.ac/Projects/MedLands/LITHUANIA.htm) • [4](https://erenow.org/postclassical/crusades/643.php) |\n\n## Accession and family\n\nMindaugas successfully asserted himself over the other leading Lithuanian nobles and tribal chiefs in 1236.[1](https://www.britannica.com/biography/Mindaugas) • [2](https://www.lrt.lt/en/news-in-english/19/1445400/coronation-of-lithuania-s-king-mindaugas-fact-fiction-and-politics)\n\nHis wife was Morta, who was crowned together with him in 1253.[6](https://www.ldkistorija.lt/the-last-medieval-kingdom-the-coronation-of-mindaugas/) • [3](http://fmg.ac/Projects/MedLands/LITHUANIA.htm)\n\n## Reign: policies, administration, and wars\n\nConversion as policy: in 1250 or 1251 Mindaugas accepted baptism from the Livonian Knights.[1](https://www.britannica.com/biography/Mindaugas) • [9](https://w.wilanow-palac.pl/pasaz-wiedzy/ksiaze-litewski-mendog-mindaugas) The baptism was organized by Andreas von Stirland, Master of the [Livonian Order](https://www.edgepedia.org/livonian-order).[3](http://fmg.ac/Projects/MedLands/LITHUANIA.htm) • [8](https://www.valstybingumas.lt/EN/saltiniu-apzvalga/LDK-laikotarpis/Pages/default.aspx) On 17 July 1251 [Pope Innocent IV](https://www.edgepedia.org/pope-innocent-iv) recognized [Lithuania](https://www.edgepedia.org/lithuania) as a Christian state by a bull asserting papal supremacy over Lithuania, which authorized the Bishop of Chelmno to crown Mindaugas king and provided for a bishop and a cathedral.[4](https://erenow.org/postclassical/crusades/643.php) • [7](https://www.xn--meb.pisz.pl/Kr%C3%B3lestwo_Litwy_(1251%E2%80%931263))\n\nOn 6 July 1253, according to medieval coronation ceremonial, the Bishop of Chelmno, Henryk, crowned Mindaugas and his wife Morta; the ceremony probably took place at his seat in Nowogrodek, though some historians place it in Vilnius.[6](https://www.ldkistorija.lt/the-last-medieval-kingdom-the-coronation-of-mindaugas/) • [9](https://w.wilanow-palac.pl/pasaz-wiedzy/ksiaze-litewski-mendog-mindaugas) The baptism, however, concerned only his closest family, not his court, let alone the inhabitants of the principality.[10](https://kurierwilenski.lt/2023/07/06/koronacja-mendoga-krok-ku-europeizacji-litwy/)\n\nThe mid-1250s brought reverses. In 1259 the southern borders of the state were invaded by the Mongols.[7](https://www.xn--meb.pisz.pl/Kr%C3%B3lestwo_Litwy_(1251%E2%80%931263)) • [11](https://kurierwilenski.lt/2024/07/06/wladca-poganskiej-litwy-ktory-wylamal-sie-ze-schematu/) In 1260 the Samogitians crushed the united army of Livonia and Prussia at the battle of Durbe, in present-day Latvia, the Order's most overwhelming defeat of the thirteenth and fourteenth centuries; the Lithuanian and Samogitian forces were led by Mindaugas's sister's son, Prince Treniota.[4](https://erenow.org/postclassical/crusades/643.php) • [10](https://kurierwilenski.lt/2023/07/06/koronacja-mendoga-krok-ku-europeizacji-litwy/)\n\nAfter Durbe, Mindaugas changed course. In 1261, at the request of the Samogitian confederation fighting the Order, he extended his power over [Samogitia](https://www.edgepedia.org/samogitia) and declared war on the Teutonic Knights, which caused the flight of the clergy, including the missionary bishop Christian, who had already resigned the Lithuanian diocese in 1259.[9](https://w.wilanow-palac.pl/pasaz-wiedzy/ksiaze-litewski-mendog-mindaugas) • [10](https://kurierwilenski.lt/2023/07/06/koronacja-mendoga-krok-ku-europeizacji-litwy/) One history states that in 1261 he returned to paganism and expelled Catholics from Lithuania;[5](https://erenow.org/postclassical/oxford-history-poland-lithuania-volume-i-making-polish-lithuanian-union-1385-1569/4.php) another holds that it is believed he gave up Christianity after Durbe, but whether he really returned to paganism is not known.[10](https://kurierwilenski.lt/2023/07/06/koronacja-mendoga-krok-ku-europeizacji-litwy/)\n\n## Political influence\n\nThe coronation enabled Mindaugas to establish the position of a sovereign ruler among the Christian kings of Europe and strongly influenced the creation of the Lithuanian state.[6](https://www.ldkistorija.lt/the-last-medieval-kingdom-the-coronation-of-mindaugas/) Lithuanian statehood was built under the influence of three new factors: the idea of crusades, the conviction that the Apostolic See was the only authority granting legitimacy to royal power, and the Mongol invasions.[12](https://mediewisci.org/gniezno/wystapienie,566,chrystianizacja-i-ksztaltowanie-panstwa-litewskiego:-przypadek-krola-mendoga-w-kontekstcie-sredniowiecznej-teologii-politycznej.html)\n\nThe kingdom itself remained a temporary episode: Mindaugas and his direct descendants who could claim the crown were killed, so the coronation did not acquire continuity, and the recognized status of the kingdom was never reached again, though the monarchy remained the main form of power.[6](https://www.ldkistorija.lt/the-last-medieval-kingdom-the-coronation-of-mindaugas/) After his death Lithuania turned back to paganism for more than a century, and his successors, the grand dukes Vytenis, Gediminas, and Olgierd, continued negotiations about baptism.[8](https://www.valstybingumas.lt/EN/saltiniu-apzvalga/LDK-laikotarpis/Pages/default.aspx) • [11](https://kurierwilenski.lt/2024/07/06/wladca-poganskiej-litwy-ktory-wylamal-sie-ze-schematu/) Once Lithuanian statehood had emerged, it never faded away.[8](https://www.valstybingumas.lt/EN/saltiniu-apzvalga/LDK-laikotarpis/Pages/default.aspx) \n\n## End of the reign and succession\n\nIn autumn 1263 Duke Daumantas of Nalšia, whose wife had been kidnapped by Mindaugas, allied with Treniota and killed the king and two of his sons, Ruklys and Repeikis; the princes were dissatisfied with the king's harsh rule.[4](https://erenow.org/postclassical/crusades/643.php) • [7](https://www.xn--meb.pisz.pl/Kr%C3%B3lestwo_Litwy_(1251%E2%80%931263)) Treniota then proclaimed himself ruler of Lithuania (1263–1264).[4](https://erenow.org/postclassical/crusades/643.php) • [8](https://www.valstybingumas.lt/EN/saltiniu-apzvalga/LDK-laikotarpis/Pages/default.aspx)\n\nAfter Treniota's proclamation, Vaišelga defeated the conspirators, and in 1267 voluntarily renounced the throne, handed it to Svarn, and returned to monastic life; he was murdered in 1267 by Lev, King of Galich.[8](https://www.valstybingumas.lt/EN/saltiniu-apzvalga/LDK-laikotarpis/Pages/default.aspx) • [10](https://kurierwilenski.lt/2023/07/06/koronacja-mendoga-krok-ku-europeizacji-litwy/) • [3](http://fmg.ac/Projects/MedLands/LITHUANIA.htm) After three rulers in five years, the strong pagan warrior Traidenis came to power (1268–1282), stabilized the state, and successfully fought the Knights.[8](https://www.valstybingumas.lt/EN/saltiniu-apzvalga/LDK-laikotarpis/Pages/default.aspx) • [13](https://wilno.tvp.pl/94158964/mendog-tworca-panstwa-litewskiego)\n\n## Historians' assessment\n\nMindaugas is considered the founder of the Lithuanian state and the first Lithuanian ruler to become a Christian.[1](https://www.britannica.com/biography/Mindaugas) • [14](https://www.encyclopediaofukraine.com/display.asp?linkpath=pages%5CM%5CI%5CMindaugas.htm) His conversion is read as pragmatic, undertaken to strengthen a rule that was very weak.[2](https://www.lrt.lt/en/news-in-english/19/1445400/coronation-of-lithuania-s-king-mindaugas-fact-fiction-and-politics) In the epoch of Mindaugas the state was perceived primarily not as the monarch's possession but as a land inhabited by people connected with their ruler by special relations of service and friendship, and the institutionalization of the ruler's power was completed only during the reign of Vytautas, generations later.[15](https://bibliotekanauki.pl/articles/969587.pdf) His assassination has been seen as a warning that there were limits to charismatic power.[5](https://erenow.org/postclassical/oxford-history-poland-lithuania-volume-i-making-polish-lithuanian-union-1385-1569/4.php)\n## References\n\n1.
